T ittle/tom ii'ynmg emiennq Be. it known that l, Gnon'on \V. Woman, a citizen ol' the United States, residing in the eity ot )Iow York, borough of Manhattan, in the county ol' Xew York and ihate ol' Xew York, have invented. a new and useful. improvement in ()[')tll.\lt3ttl.llttl Frietion loii (this or Vessels, ol' \\'l1l('l) the following is a speeilieation. l9

sores t'or eans or other vessels, and more partieularly to improvements in elosnres tor ants ol' the hind or class having t'ull open months or upper ends, and in which no an*' 5 nular top is employed to receive the removable eap or (oYe i. .il leretol'ore in cans oi" this kind or elass having no annular tops, so that the mouth or opening maybe 01' substantially the toll diameter olf the body ot' the ran 30 or vessel, eonsiderahle dlllienlty has heretofore been experieneed in prai-tieally ell'eeting a tight and seenre elosure ot' the friction eover on the body ot' the ean or vessel, owing to the t'aet that while the eorer is stamped in one pieee out ot a hlanlchy suitable dies, and thus ran he made unit'orinly ol' the exael diann'ter and size retpiihd, the bodies ol' the eans, being made by forming a reetangular lilanli into eylindrieal shape and uniting its meeting ends by a side seam, the eanbodies necessarily vary in size or diameter more or less, so that the required tight l'rietion tit between the llange ol the rover and the ean body, neeessary to etleet a tight and seeure '35 closure, eannot .b'e nnil'ormly obtained, the

can bodies sometimes tilting the rover too loosely and sometimes too 'htly, and thus causing the llange ol' the eorer to he st retehed )1'l)l'()li(l1.

tall open mouthed l'ri tion eover -an of a simple, etlieient and durable eonstroetion eapable of being tightly and seeurely elosed, and at the same tim readily opened.

i\l invention eons s in the means i employ to praetieally aoeompltsh this objeet or result; that is to say, it eonsists, in connection with an open mouthed an body, ol' any suitable kind or construction, 01' a t'riotion cover therefor having a flange surrounding and embracing the upper end of the :an 1 body, and furnished with a slit,

aince extending atirirstlie cover flange, and

provided with an, integral lipprojeoting from i5'the lovreretlgo'of the cover flange on eaclt My invention relates to t'rietion top elo The object of my: invention is to provide a rot or severl l l l slit-bridging; lip of the cover th n side of the slot or slit \vhieh severs or divides the cover llange, so that while, the cover llange is thus made eontmuous by its integral l )rbjeeting lip, the llai'ige is, nevert'lwless,

adapted to expand or open at the slotfor slit to the extent neeessary to -ause it to aeeominodate itsell in the size of the can body, and thus elleet a tight and secure elosure. The slit or slot extending aeross the rover tlange may also, prel'erably, extend into the tip which projects trom the lower edge of the. cover llange, simply leaving at't'he lower portion ot the lip sullieient body oi metal to give the requi site strength to the elast'ie or expandible hand l'ormed by the severed Cover llange and the lip, and whieh surrounds and embraces .the an body and g es the cover the requisite tight elastie grip or l'rietional littjhereon to properly seal the am and compress the sealing dist; or gasket, n'liieh is interposed l)ttween the rover and the upper end ol the an body: as by this means l am enabled to readily and eonveniently open my improved ran by simply bending or folding the li-p np side ol' the slit to spring apart and thereby loosen the grip of the cover llange on the can body so that the cover may be removed. To taeilitate this operation the top of the cover may prelerahly be provided with a rt-groove, or other channel extending diametrieally aeross it except at the annular rim portion which compresses the sealing disk or gasket against the upper edge ol the ean body. it prel'errial however my elastie expandihle t'rietion eover with eontinuous lipped rover llange, having a slit or slot extending aeress the cover llange. may be provided with arow of perforations, a seore or other \reatw ened line extending aeross the lip so that the lip may be readily tnolten olt and the ('oll-- t-inuity ol' the rover tlange thus destroy d l e; entirely removing the lip whieh bridg s he slitied, slotted or severed portion oi the rover tlange. 01' in openin rj the ran it desired the lip may be broken oil by simply repeatedly bending it up and down without providing it with any perforations, score or w ialiened line to facilitate its removal.

As before said however, 'prel'er to practice my invention without breaking oil or removing the by siin bending itlnpward against the to 1 1gasket, and D the triction cover. 40

out, there is a corner space between the ciroular cuts which permits the projection of the lip on two sideswithout taking up any additional stock, the lip being cut entirely frorn the waste space or stock between the centers. My invention also Consists In the 'novel construction of parts and devices and in the novel combinations ol' parts and devices herein shown or described.

in the acconipai'iying drawing, forming a part ol this specification, Figure 1. is a side elevatioii, partly in vertical section, of an open mouth friction covencan embodying my invention; Fig. 2 is a plan view, Fig. 3 is a front elevation, showing the slit or slot bridging lip after it is bent up'against the flan e ,ot the cover ire iarator r to o Jcnin b 4 b the can; lug. 4 is a partial section on line 1s a side elevation, partly in vertical section illustrating a modihfication; Fig. 6 is a side elevation, partly in vertical section, illustrating a lurther modification. Fi 7 illustrates a modi'tication in n I b v n which my improvement is ap plied to a vessel "havin an external shoulder on the body a I a 3 5 thereof.

{in the drawing A represents the can body having the customary side seam a, B the "lower head or bottom, 0 the sealing disk or The can Ody-AL has an open upper end or mouth a preferably of the full diameter or substantially the'full diameter of the body. This upper? end a may, if desired, have a roll, fold, or rounded shoulder a as shown in Fig. 5, to give a better seat or hearing for the upper end of the can against the sealing disk or gasket C. Or, it preferred, the upper end of the can body may be slightly contracted in diameter, as indicated at a in. Fig. 6.

Ordinarily however I prefer to make the upper end or sealing seat a. of the can body;

plain or straight, as indicated in Fig. Iv

The lower head .or bottom B ot the can may be secured to the can body by any suit- .able 'l'orin of scam, toldcd or soldered, custop arily used in the art.

he sealing disk or gasket 0 may be made of anysuitable construction or mater al cus- I I tomarily employed for this purpose, such 0 for example paper or cardboard laced with parchment paper or other non-soluble sur' face, which is tasteless or not injuriousto the material contained in the can 01 iv'essel. -The sheet'metal cover Dot the can has an 35 integral flange (Z which surrounds," nbraces and tightly engages the upper portion of the can body, and is adapted to be terribly and tightly driven upon the can body so as'to engage the same with a tight grip or l'ric- Lional {it sutlicient to hold the sealing disk or gasket properly compressed, and thus produce a tight and secure closure ol" the can. This cover flange d severed at (.l, :the severed linebeing preferably l'oianed by a narrow slot (1 as shown in Fi s. 1 and 4 or r its lower edge, and which bridges the severed portion of the cover flange, and thus while preserving the continuity of the cover flange, making it nevertheless elastic or cxpai'idible, so that the flange may readily accommodate itself to the variations in the size or diameters of the can bodies to which the covers are to be applied, so that the cover will always properly and tigl'itly tit or l'rictionally grip the can body and thus produce a tight and secure closure. The integral lip d serves not only to elastically bridge in bent line the severance in the cover flange but also as a finger piece to loosen. the cover flange on the can body, thus enabling the can to be readily opened with the lingers and without the necessity ol employing any separate opening tool.

The length or depth of the slit bridging lip (Z ol" the covcr flange preferably somewhat. exceeds the width of the cover flange at, so that when this lip d is bent upward against the cover flange, preparatory to opening the can, the continuous portion of the lip at the base or lower end of the severed line or cut portion (1, will be substantially in line with the top tare ot the cover to facilitate the springing apart of the two parts (1 (Z of the cover flanged on each side of the severing line d, indicated in Fig. 4. To further facilitate this action. the top or disk portion D of the cover is, preferably, furnished with a V or other grooveT) extending dian'ictrically across the cover excepting at the marginal or rim portion d thereof, which forms the seat or bearing for the sealing disk or gasket this V diametric'groovc or channel serves somewhat a pivot or axis for the two parts of the cover to swing or spring apart about, as will be readily understood from Fig. 4. )The lower extremity of theseyerance d may, preterably, have a rounded portion (1, as this construction mil'djsto th strength and expansibility of the lip (1" which bridges the slitted, slotted or-sovered'end portion of the cover flange.

.In the modification illustrated .Fi 5

the integral continuous slit bridging lipzftugof' the cover flange, is provided with a score or weakened line d extending across the 'lip dflpreferably in line with the lower edge of the never flange, to enable the lip to be readbreken o'i'i' or removed in opening the can or veal .jind in Fig 6 a similar modified. ermstruomon is shown that the weakened line is formed by a. row oi perforations d instead a score of weakened line.

in the modification illustrated in Fig. 7 I have illustrated my inventionas a )plied to a jar or vessel fliaving an external shoulder under which the lower edge of the cover flange may be bent or criinped, and in which the lip projccfing from the lower edge of the cover llango and bridging the severances in the covcr llange is adapted to be broken oil at or near the lower edge of the rover 'tlango Billlpl) by repeated bendings without any score or weakcned line as hereinhet ore mentioned.

The cover I) is, prelerablg, lurnished with ;.a peripheral or annular recess (1 to receive 'fhe edge or run ol the sealing disk or gasket (1, the same serving to hold the sealing disk or gasket 1 in place, and also to give a better hearing for the upper end or gasket seat (1 ol' the can body against the sealing disk or gasket, especially when the can body is made plain. or straight at its upper end, as shown in Figs. 1, 3% and l.

By providing the cover with two integral lips d" and two eoverances d diametrically opposite each other and in line with the groove or channel I), the cover is adaptcd to he very easily rcnmvcd when the intcgral ii is (11 are bout u iward u' ninst thc flan 'e d as will bc rcadilv undcrstood from i igs. 2, 3 and i oi'ihc d owing! li dcsircd thc wall ol the friction covcr l) may bc lurnishcd. with a small vent opening d to pcrinif air to cscapo from the interior oi thc can while the friction cover is bcing 'torocd ironic thcrcon, this \"ontopening bring soalcd or closcd by the sealing disk or gasket.
